Studies of the motion of the anterior heart wall and central arteries using radiokinetocardiography

: A total of 21 subjects without signs of circulatory abnormalities were examined by a noninvasive intrascopic cineradiocardiographic technique which involved recording of an electromagnet superhigh-frequency signal reflected from the heart and central arteries. The oscillations occurred in the initial segment of an echo signal were explored. Cineradiocardiography was demonstrated to allow the motions of the arterial wall of the ventricles, atria, and a proximal portion of central arteries to be studied. The areas for applying an aerial to the front chest wall were defined to record the motions of anterior heart walls and central arteries. The features of appropriate cineradiocardiograms were described.
